Fraser, C. E. Ovid(University of Wisconsin, Madison),and David T. Berman. Type-specific antigens in the psittacosis-lymphogranuloma venereum group of organisms. J. Bacteriol.89:943–948. 1965.—Antigens of 14 strains of the psittacosis-lymphogranuloma venereum (PLV) group of organisms were prepared by treating purified particles with deoxycholate and trypsin. In complement-fixation tests of these antigens with the homologous and heterologous antisera, specific serotype differences were observed. Application of the method of specificity differences permitted placement of the 14 strains into 7 subgroups. The possible value of these techniques in immunology, epizootiology, and taxonomy of the PLV group is discussed.
